# Call Tools with Image Prompt

Some language models that support vision capabilities accept images as part of the prompt. Here are some of the different [formats](/docs/reference/ai-sdk-core/generate-text#content-image) you can use to include images as input.

```ts
import { generateText, tool } from 'ai';
import { z } from 'zod';

const result = await generateText({
  model: 'openai/gpt-4.1',
  messages: [
    {
      role: 'user',
      content: [
        { type: 'text', text: 'can you log this meal for me?' },
        {
          type: 'image',
          image: new URL(
            'https://upload.wikimedia.org/wikipedia/commons/thumb/e/e4/Cheeseburger_%2817237580619%29.jpg/640px-Cheeseburger_%2817237580619%29.jpg',
          ),
        },
      ],
    },
  ],
  tools: {
    logFood: tool({
      description: 'Log a food item',
      inputSchema: z.object({
        name: z.string(),
        calories: z.number(),
      }),
      execute({ name, calories }) {
        storeInDatabase({ name, calories }); // your implementation here
      },
    }),
  },
});
```
